First: As I mentioned in my e-mail, a Euclidean valuation on an integral domain R is a function u : R* → N (where R* is the set of nonzero elements of R, and N includes 0) with two properties: (1) if a,b E R*, thern (a) v(ab); and (2) if a, b R and b 0, then there exist elements q,r R such that a-bqr and either 0 or v(r) < v(b). Prove that if o is a Euclidean...

Suppose that a sequence {Zn} satisfies Izn+1-Znl < 2-n for all n e N. Prove that {z.) is Cauchy. Is this result true under the condition Irn +1-Fml < rt Let xi = 1 and xn +1 = (Zn + 1)/3 for all n e N. Find the first five terms in this sequence. Use induction to show that rn > 1/2 for all n and find the limit N. Prove that this sequence is non-increasing, convergent,
For three sequences X[n],y[n],z[n], assume that Y(w)= X(-w) and (w)= X(w + TT) in the Fourier domain. In the z-domain, what are Y(z) and Z(z), respectively? A. X(-2) and - X(z) B. X(- z) and X(2-1) c. -X(z) and X(2-1) D. -X(z) and X(-2) E. X(z-) and X(-2) F. X(z-1) and - X(z) G. None of the above.
Definition of Even: An integer n ∈ Z is even if there exists an integer q ∈ Z such that n = 2q. Definition of Odd: An integer n ∈ Z is odd if there exists an integer q ∈ Z such that n = 2q + 1. Use these definitions to prove only #5: 2. Prove that zero is even. 3. Prove that for every natural number n ∈ N, either n is even or n is odd. 4....
